$abc = "yes";

exec_perl( '$abc', ` $abc =~ s/yes/YES/g; (($abc)); ` );
console.log ( $abc );  
// =>  YES

$abc = 'text of $abc var.'; 
var perl_stm =  `
     $abc= $abc x 2;
     $abc =~ s/text/TEXT/g; // use your comment
     (($abc));  # another comment style,define return var
`;

// var ret_obj = app.e_pl ()... // also works 
var ret_obj = exec_perl ( 
    '$abc',     // caution! it's name of var, not value
    perl_stm
);
console.log( $abc ) ; 
// =>  TEXT of $abc var.TEXT of $abc var.
// console.log ( ret_obj.ans );
